Specification of Letters Patent.

Patented Oct. 6, 1908.

Application filed September 4, 1906. Serial No. 333,100.

To all whom it may concern:

Be it known that I, HARRY I. ILLING- WORT a citizen of the UnitedStates, and a resident of Swampscott," in the county of Essex and Stateof Massachusetts, have invented an Improvement in Machines for Snippingand cementing Shoe-Uppers, of which the following. description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

My invention is a machine for applying cement to curved edges such asshoe uppers and the like and snipping them at the curvature forpreparing said leather pieces for folding.

The usual custom is to carefully brush the skived surfaces of leatherpieces with rubber cement, allow the cement to dry, and then snip andfold the leather pieces. This is objectionable in many ways, is wastefulof the cement, lacks neatness because of the stringy character of thecement, is slow, expensive, tends to daub the. snipping and foldingapparatus and it is apt to spread the cement beyond the skived surfaceto which the cement should be confined. x

Accordingly my apparatus includes means for snipping the curved edgejustprior to the application thereto of the cement, and means for applyingthecement in a limited amount at the precise point which it is desiredto cement, said applying means .being' automatic and including mechanismfor preventing the application of any more cement than is required.

My mechanism is adjustable to conform to different sizes of uppers andpreferably contains an adjustable gage for regulating the position ofthe vamp, an adjustableseries of cement depositors preferably in theform of tubes, for depositing a series of globules or small daubs orsmears along the entire length of the skived surface, an automaticdelivery apparatus for supplying exactly the amount of cement required,an expansible or adjustable snipper conformable to the different widthsof uppers, and mechanism for causing the snipper and cementer to contactwith the leather dissimultaneously, although preferably moved in unison.

The further constructional details and advantages of my invention willbe pointed out more at length in the course of the followingdescription, reference being had to the accompanying drawings, in whichI have illustrated my invention as adapted to operate on shoe Vamps oruppers, although it 'will be understood that it may readily bechanged'tooperate on various other shoe parts which it is usual tocement as a preliminary step to the stitching operation.

In the drawings, Figure 1 is a view in side elevationpartly broken awayand sectioned, showingmy cementing machine in position to receive a vampor shoe upper to be folded; Fig. 2 is a top plan view thereof, thecement depositing portion of the apparatus being omitted and a shoeupper being indicated in place in dotted lines; Fig. 3 is a verticalsectional view on the line 33 Fig; 1; Fig. 41s a top plan view of thecement applying portion of the apparatus; Fig. 5 is an enlargedfragmentary top plan view of the snipping end of the machine,

the cementerbeing removed; Fig. 6 is a horizontal sectional view on theline 66 Fig. 1; Figs. 7 and 8 are vertical sectional views showingrespectively the long snipper knife and the short snipper knife andadjacent parts; Fig. 9 is a sectional elevation of the cement tank.

On a suitable frame or'base 1 is mounted at the rear on a standard 2 acement tank 3 and at the front of the machine is a gage composed of twoparts 4, 5, and a cemeter 6 supported and operated by an arm 7 securedto the'shaft 8, vertically movable in a hearing 9 andoperated by a rockshaft 10 and foot lever not shown, connected thereto by a rod 11;

Viewing more particularly Figs. 1, 3 and 6, a transverse depression inthe bed is formed by a bed piece 12 and is provided with a centralgrooved way 13 and opposite surface ways 14, 15, on which rest oppositeguide frames 16, 17, above which is secured a bed plate 18 flush withthe top of the frame, slotted to permit lateral movement of verticalguide posts 19, 20 in opposite pairs. These posts serve to guide thecementer both vertically and laterally. For the latter purpose theframes 16, 17, are provided with studs 21, 22 respectively, engaged bythe cam grooves 23, 24: of an adjusting lever 25 centrally pivoted at 26so that as the lever is swung to the right, Fig. 6, the frames areseparated and as it is swung back to the left they are brought together.They are shown in the drawings as brought together, and are separatedfrom that position for larger or wider throats of vamps. The adjustinglever 25 is provided with a handle 27 and a dog 28 arranged to engage anotched sector 29 whose graduations indicate the different sizes towhich the machine may be set. .he guide rods 19,20 are moved apart bythe shifting of the handle from the position shown in Fig. 2, and, assaid guide rods are arranged out of transverse alinement with eachother, as clearly shown in Figs. 2 and 6, the gage parts 4, and all thecooperating parts of the machine may thereby be brought close togetherfor the smallest size of vamp wnich it is desired to cement with mymachine.

The cement applier comprises preferably a chamber 30 which extendsbodily over the entire surface to be cemented, and is composed of alower casting 31 and an upper casting 32, the lower casting havingbearings 33 for the rods 19, 20, said bearings extending up through theupper casting as clearly shown in Fig. 1, so as to make a tight andconvenient joint, and the bottom of the casting 31 is provided with aseries of closely spaced tubes 34: removably secured therein by screwsand arr; nged in a line following the curvature or exact direction ofthe skived surface which is to be cemented, as is plainly shown in Fig.l. The two castings are clamped tightly together by any suitable means,as by screws 36, and from the upper side of the cement chamber projectears 37 in which are loosely mounted short rods or stub shafts 38 shownclearly in Fig. 2, fixedly securedv at their middle portion by a yoke 39and an tl-shaped link 40, see Figs. 1 and 3, pivoted at- 41 to said yokeand at $2 to the arm 7 before mentioned. Thus it will be seen that asthe arm 7 is raised the cementer is guided accurately on the four guiderods 19, 20 and is readily lifted in balanced position by the yoke 39and pivoted link a0. It slides freely up and down on said rods, whichcause it to descend with the utmost accuracy on the leather, and also itis freely adjusted laterally with the utmost nicety by the 'am leveradjustment which separates said rods 19, 20 or brings them together. Thecement is delivered to the cement chambers by pipes 4;), 4%, connectedby a flexible section 4:5 with passages 46 from the tank 3.

The shape of the cement chamber and the arrangement of the cementapplier in two separate parts, as shown clearly in Fig. 4, permits thedelivery tubes or nipples to come close together at the forward end, soas to make a continuous cement application, and also permits them to bearranged in any desired curvature, either parallel or flaring. beingherein shown as flaring at their rear ends. I have provided means forcontrolling the cement delivery simultaneously for all the tubes, saidcontrolling mechanism being arranged air tight above the cement,

forcing the cement forward by a positive feed and preventing its feedingby gravity or unduly in any way by the tight fit of a pistenlikecontrolling head -l-T carried at the lower end of a vertical shaft loprovided with a rack 49 guided in a transverse plate 50 and engaged by aline toothed pinion 5] rotated by a transverse shaft 52 and normallyheld in engagement with said rack by a spring 53 and provided with ahand hold 5- by which it may be retracted when desired, see Fig. 2. Theshaft 52 at its farther end carries a friction ratchet wheel 55 whosesmooth periphery is engaged by an eccentric hub or pawl 56 'arried by alever 57 pivotally mounted on said shaft and operated by the raising andlowering of the reduced upper end of the shaft 58. being held inadjustable position by a nut 59 threaded on the outer end of the shaft58 and a spring ('10. the amplitude of movement of said lever 57 beingregulated by a threaded post ()1 carried at its extreme rear end. seeFig. '1. The eccentric dog 56 is normally held in biting engagement withthe rim of the wheel 55 by a weight 62, so that the lever 57 is alwaysfree to move upwardly without rotating the wheel 55, but the moment thelever 51' begins to move downwardly the weight 2 causes the pawl or dogto to bite or pinch against the rim of the wheel 55 which const itutes,with the pawl, a friction pawl and ratchet mechanism, and therebypositively rotates the shaft and pinion 51. causing the tig it pistonhead 4-7 in the cement tank to move down 'ardly exactly the distancerequired. Vhen the cement has become practically exhausted and a freshsupply is needed, a. 'alve ($3 operated by an upwardly extending handle(S-l is opened in the head l? to relieve the suction or air pressure. sothat the latter may be quickly raised. and the pinion 51 is then slidlaterally against the pressure of the spring 5 out of engagement withits rack. and thereupon the operator grasps a transverse head or handle(35 at the upper end of the latter and pulls the piston headquickly,straight up to the top of the tank. thereupon letting go of thepinion. which instantly meshes with the rack and holds the parts inplace while the tank is being filled through the "alve opening and thenthe valve (33 is secured back in place and the machine is again ready tooperate.

The snipper mechanism is operated simultaneously with the cementapplier, by the same means, and is best shown in Figs. l--l l. 5, T andS. It comprises a central group of cutter knives, herein shown asconsisting of two knives (30, having their cutting edges extendingforwardly at their top ends and having L-shaped projections (37 at theirlower ends mounted in grooves in the upper end of a post or knife'arrier (3S and held down by clamping plates (39, said post beingclamped to a casting having an ear or horizontal flange 71 extendingrearwardly between collars 72, 73, on vertical knife carriers 74, 75,said flange being slotted at 76 to permit lateral movement of saidcarriers 74, 75, which are journaled inbrackets 77, 78 projectingrespectively from the front sides of the slide frames 16, 17, whichcarry the opposite sides or portions of the cement applier. At theirupper ends the knife carriers 74, are provided with a series of knives79 proj ecting in range with the cutting ends ofthe long knives 66, saidknives 79 having their shanks 8O engaged by a plate 81'retained inclamping position by a cap 82 and screw 83. Below the cutting ends ofthe knives 66 and 79, the machine is provided with steel plates 84, 85,slotted at 86 in exact alinement with the knives, so that'when theleather is slid into position against the gages 4, 5, it will be snippedor slitted evenly and neatly, exactly as required. The snippers orcutting knives are depressed ahead of the cement applier, and aftercutting, remain beneath the leather while the cement is being applied,as will be readily understood viewing Fig. 1. I provide a central groupof knives 66 and later-' ally adjustable side groups of knives 79, so asto prevent having a wide uncut gap at the middle, as would be the caseif I only had two groups. The lateral adjustment for difierent sizes isaccomplished by moving the side groups away from the central group,which leaves a slight gap, but the adjustment is thus divided betweentwo groups and hence is less than would otherwise be the case, and infact becomes a practicably negligible quantity. The slotted plates 84,are fastened by screws 87 to projections 88 which extend forward fromthe frames16 and 17. A central stationary plate 89 is provided withslots to correspond to the two stationary knives 66, being fast on astationary ledge or arm 90 of the main frame of the machine.

The gage members 4, 5, have cars 91 surrounding the gage rods 19, 20, sothat they are simultaneously adjusted by the ,movement of said rods. Itwill be understood that I have herein shown merely the preferredembodiment of my inventiomand its application to the particular part ofa shoe called the upper or vamp, but my invention may be embodied invarious other modified constructions, and its range of usefulness is notlimited to any particular part of the shoe. The clamping casting 7 0 ofthe snipper mechanism is hifurcatedat 92 to receive a roll orcrosshead-93 carried at the end of an arm 94 faston therock shaft 10,which serves to raise and lower the snipping mechanism, and the cementapplier is simultaneously raised and lowered by an arm 95 engaging asocket pieceor casting 96 at 97 as clearly shown in Figs. 1 and 6. AlsoI provide at the front side of the casting 96 projecting arms which forma guideway 98 between them for receiving a flat direction arm 99,projecting from the rock shaft 10, which serves to hold the cementapplier in accurate alinement and prevents any possible lateral swingingmovement thereof, which would tend to cause the same to bind against theadjusting posts .19, 20. The direction arm 24 gives smoothness andprecision of movement.

From the foregoing description the operation of my machine will bereadily understood. The operator simply places the leather piece whichis to be snipped and cemented, in proper position agamst the gages 4, 5and then depresses the foot lever, which rocks the shaft 10 and therebycauses the simultaneous downward movement of the snippers and cement orpaste applier. As the snipper is nearer the leather than the pasteapplier it cuts and passes through the edge of the ,leather first, andjust as it reaches its lower position beneath the leather the oppositeseries of tubes of the paste applier lightly touch the leather and leavea series of smears or globules of cement along the skived surface of theleather exactly where they, are required. Just as the cement appliercomes in contact with the leather the operator pulls the work slightlyaway, meanwhile causing the rock shaft to rock in the opposite directionso as to raise the cement applier slightly, the result being that thecement deposits are dragged into a continuous line as desired, as thework is being removed. The operator quickly be comes skilled in thefeeding and removing movement of the work as above outlined, so that thework progresses rapidly, the cement is dragged into a continuous line,and the snipping and cementing proceed rapidly. All the parts move upand-down together under the action of the foot lever or other actuatingpower, the snippers moving in unison with the cement applier, andperforming their cutting operation simultaneously with the applicationof the cement. If a larger pattern is to be operated upon, the operatorswings the hand lever 27 over to the right Fig. 2 to the extentindicated by the'graduate'd sector 29 for that size. This movement actsthrough the cams 23, 24 of the adjusting lever 25 to separate the posts19, 20 and thereby simultaneously adjust the gages, the side members ofthe snippers, the corresponding portions 84, 85 of the table, and thetwo parts of the cement applier. The cement delivery tubes are always inexactly the correct relation to the gages, and the same is true of thesnippers because of the simultaneous adjustment of all the parts.Moreover, this adjustment is exceedingly simple, being accomplished by asingle movement of the hand lever 27. As already explained, the cementdelivery is under absolute control, by reason of the air-tightarrangement 01 the cement tank which regulates the gravity flow or feedof the cement. If enough cement is not being delivered, the amplitude ofmovement of the friction pawl 56 is increased by raisingthe adjustingscrew 61, and if desired, the nut 59 is correspondingly adjusted.
